Apparatus for the gastight fastening of a foil container

Abstract

In order to reliably and safely secure a flexible container, such as a glove, to an opening in a housing, which opening is surrounded by a tubular stud projecting outwardly from the housing, the stub is provided with at least two grooves in its interior wall, each groove having an omegoid cross-section, and the flexible container is clamped in each groove by a clamping ring having a circular cross-section corresponding to that of the central portion of the cross-section of its associated groove.

What is claimed is: 
     
       1. In a device for fastening a flexible foil container to a housing, the device including a tubular stud surrounding an opening in, and projecting outwardly from, the housing, the stud being provided with circumferential grooves, and a clamping ring arranged to be secured in each groove for clamping the flexible foil container in the groove, the improvement wherein: there are at least two said grooves in the interior wall of said stud; each said groove has an omegoid cross-section; and said clamping ring for each said groove has a circular cross-section corresponding dimensionally to the center arcuate section of said groove cross-section. 
     
     
       2. An arrangement as defined in claim 1 wherein said stud is provided with a further circumferential groove in its exterior wall. 
     
     
       3. An arrangement as defined in claim 2 wherein said further groove is located between two of said grooves in the interior wall of said stud, relative to the direction of the axis of said stud.
